There's a fairly good chance the legs will come off easily. If so, that's probably your best option. Otherwise, you might look at getting a hitch installed on your car (probably ~$200) and then renting a trailer (~$15) from Uhaul. Uhaul can sell you the hitch and install it. The cost will be a bit less than renting a truck, but it will be easier to drive, and then you will have a hitch on your car you can use for other things later (bike rack, ski rack, towing, etc.)
If you're handy at all you can even put it on by yourself. You can buy the hitch for ~$100-$170 and put it on in an hour or so. There are often pre-drilled holes already there. You just need to bolt it on. If you are considering that at all, though, you should definitely look up some instructions first.
